Hello everyone, Long time lurker, first time poster. This forum is an invaluable tool in my quest for maintenance and performance upgrades. Back into mustangs after a 10 year break. Previously had a 1997 4.6 2V. My new to me 1997 Cobra was "tracked by an old man” according to the broker I...

I'm trying to perform a compression test on my 2003 Cobra, but I can't get my compression gauge to thread into the spark plug hole. It seems like there is a shoulder preventing the threads on the gauge from reaching the threads in the head. I've bought two different compression testers and...

Hey guys my name is Duncan (In2myCobra) and im 18 years old. I am a proud owned of an 01' SVT Cobra. I bought the car around 2 months ago, when something tragic happened. I spun a bearing after only 1,600 miles. I never drove hard on the car and babied the hell out of it. So now Ford is saying i...

First of all im new to svt. I recently found one i liked and had a compression/inspection done. The compression test was done at a ford dealership. They told me that it looked excellent and that all cylinders came back at 150 psi +\- 5 psi. I figured that seemed a little low. Im not sure if they...

I have been waiting on my end over the past year for somethings to finalize before I purchase a Cobra. I am finally ready and I have been planning to buy one off of Hi-End Auto (Hi-End Auto - Hi-End Auto) in VA as their inventory cannot be matched. A few new ones came in the other day and I was...

Alright. Here is the short story. Just picked up an 03 convertible with 87,000 miles. Got it inspected, tag....etc. Had it one week and the service engine light came on.
